problems. >> it is back and better than ever. >> waterproof now? >> waterproof, amazing. you take the wristband off and pop it into the headphone jack of your iphone. it tracks your sleep, calories burned, your steps taken. as you can see today i've already taken 1,668 steps, i go for 10,000 steps a day, but the cool one i like is the sleep. you can see it maps out my sleep, but not just shows me how many hours i've slept, deep sleep, slight sleep, how long it took to fall asleep, maps it out for you, and i can follow my friend mindy and travis. friends and family, you want to track the data, do that too. >> i want to find out how my family's sleeping. >> nice little option. >> fit bit is another option, if you don't want to have the bracelet i have, this is more discreet, you can have it on your bra, your pants. >> that's much more discreet. >> well, you don't see it, al. let's get with the program here. >> it's lighting and beeping.
